I don't have a laptop that has an OEM install, so I may be incorrect about some of these suggestions. If your F keys will not work this way or you cannot boot to an Windows 7 Install DVD or a Windows 7 recovery CD, you may have to reinstall. You may be able to access the drive a different way to recovery your data.
But during a normal Windows 7 boot, hitting the F8 key will bring up recovery options. If you are not seeing those, there is a possibility you are not hitting (tapping) the key at the correct time. Keep trying and see if you can get some reaction. You may have to wait just a second longer before tapping the F8 key, or start a little earlier.
If you can do something to reach a Windows 7 repair system, post back. If you cannot, I do not know what else to suggest, but I do wonder how you ran the commands you say you ran...
